The Zygoma and the Symphysis: New Extra-Alveolar Sites for Long Mini-Implants
Volume 51 : Number 10 : Page 680 : Oct 2017
Long mini-implants placed in extra-alveolar areas of good bone quality and quantity can provide stable anchorage without the added cost and surgery of miniplates. The authors evaluate the potential of two new sites, the zygoma and the symphysis, in orthopedic Class III treatment.

Comparative Direct Dosimetry of Cone-Beam Computed Tomography Using Reduced Basis Projections
Volume 52 : Number 3 : Page 173 : Mar 2018
Efforts to reduce patient dosage from CBCT have focused on reducing the field of view—an impractical approach for orthodontic imaging. This study from Drs. Mah and Danforth uses direct dosimetry to evaluate the effectiveness of an alternative approach: reducing exposure by performing a half scan instead of the traditional full scan.

CAD/CAM Metallic Printing of a Skeletally Anchored Upper Molar Distalizer
Volume 54 : Number 3 : Page 140 : Mar 2020
Laser melting is an innovative method of 3D printing that has been used to produce metal rapid palatal expanders. Drs. Graf, Vasudavan, and Wilmes show how to use computer-aided design for 3D metal printing of a molar distalizer with palatal mini-implant anchorage.

CASE REPORT
Volume 57 : Number 3 : Page 169 : Mar 2023
This case demonstrates a protocol called SKAR III (skeletal Alt-RAMEC for Class III) in a completely digital workflow. Interceptive treatment of a complex Class III hyperdivergent patient is accomplished in two phases, involving rapid palatal expansion followed by miniscrew-anchored expansion and protraction.

OVERVIEW
Upper-Molar Distalization and the Distal Jet
Volume 50 : Number 3 : Page 0 : Mar 2016
Can upper molars really be distalized? This elusive query comes up whenever the topic of Class II correction is raised, yet no conclusion seemingly achieves a consensus. At least, we periodically pretend not to comprehend how correction occurs (despite the substantial number of clinical and research reports on the subject) so as to promote methods that may be in current favor. The idea that the maxilla or the maxillary dentition can be moved posteriorly to resolve a Class II malocclusion is perhaps one of the oldest and least understood concepts in orthodontics. The application of some type of pushing force against the upper arch and teeth to correct a Class II has obviously worked well enough during the past 100 years of orthodontics to perpetuate the "orthopedic" side of the specialty. The term distalization is a neologism, made up in recent years for our convenience. But while it may be an example of "bad" English, it might still be good orthodontic practice. To address whether upper molars can really be distalized, we need to address how contemporary distalization methods do what they do.
